Debian chroot for Kobo

Hi,

inspired by the Kindle OS thread I experimented with getting Debian wheezy to run in a chroot on my Kobo Touch and it runs pretty well. Xorg works fine with fbdev, just the touchscreen needed a bit of fixing in xorg-input-evdev since the driver sends out broken coordinates when a touch is ended (see the modified sources in the home directory in the image) and calibration (use xinput_calibrator or if that doesn't work do it manually in /etc/X11/xorg.conf).

To try it out put http://andreas.heider.io/kobo_debian/debian.ext3 http://andreas.heider.io/kobo_debian/debian.sh on your onboard storage, telnet/ssh to the kobo and run /mnt/onboard/debian.sh

I preinstalled some software from http://www.mobileread.com/forums/sho...d.php?t=195702 so there's a nice menu and a few somewhat working programs. But since it's debian and a fully working X-server you can run whatever you want.

I'll post some screenshots and more info tomorrow.

Great job regarding the broken coordinates, this is also an issue with my port of kindlepdfviewer, I'll see what I can come up with.

I managed to install and start-up Debian on the Kobo Touch (using the plugin interface), but the touch screen does not function properly (as was expected from the startpost)

How to do the following to fix this?

Try setting up telnet or ssh via Wifi (or usbnet if you want it to be more reliable) and execute debian.sh from there. Then you get a shell and you can run "DISPLAY=:0 xinput_calibrator".

Hi,

i've been trying to run Debian on my Kobo Touch. So i copied debian.ext3 and debian.sh to my Kobo Touch and started Debian from the Serial Console of my Kobo.

I actually see the Desktop, but touch is not working. So i tried "DISPLAY=:0 xinput_calibrator" as suggested above, but i only got: Unable to connect to X server. Same Problem with other x-Applications as xterm.

Setting some Calibration Values in xorg.conf didn't do the trick too.

Now when i am touching the screen i always get: Divide by Zero in xf86ScaleAxis.

Has anyone here figured out how to get the Touchscreen running?

Michael

Ok, i managed to fix one problem by myself: I had to set DISPLAY to :6 or :7 instead of :0. Which one can be found out by "ps ux | grep X".

But this did not solve everything: i ran input_calibrator, touched the first calibration point. Then the Cursor jumps to the next position. Now i can touch the screen on any point, the program does not accept my input.

Can anybody give me any advice?
